Morphology

intercalary + year

The adjective 'intercalary' means 'inserted to synchronize the solar year', so combined with 'year' it straightforwardly denotes a year with an insertion (an extra day). This is a normal adjective+noun composition and the meaning is directly derivable from the constituents, so a learner who knows both words would understand it.

Etymology

The term intercalary year comes from the idea of 'inserting' an extra day into the calendar, like slipping one small day into February so the seasons stay on the same dates. So it means a year with an extra day added to keep the calendar correct.
